Big main character energy here from Gemini South. Sure, the telescope conducts world-class research and captures jaw-dropping images with its 8.1‑meter mirror… but honestly, it knows it’s photogenic too. #astronomy

Do you have Gemini GMOS MOS and IFU data and don’t know how to reduce it? Don’t panic, we have here the solution for you: the GMOS Data Reduction Cookbook nsf-noirlab.gitlab.io/csdc/usngo/g... #astronomy

Want to know more about us? The US NGO is part of the NSF NOIRLab. Our main goal is to support US Gemini users in the phases of the astronomical observing cycle, from proposal preparation to data analysis. More info about us and what we do 👉 noirlab.edu/science/prog...

The US partner received 266 Gemini proposals for the 2026A semester. About 75% of those were submitted within 48 hours of the (extended) deadline (we are not looking at you 🙂)! Our Time Allocation Committee will soon review and rank the proposals, so stay tuned! #astronomy

Looking for the go-to place with all the key resources for Gemini Observatory users? Say no more! Visit our website (noirlab.edu/science/prog...) to find everything you need — from proposal preparation and data analysis to current conditions and the latest observed data. #astronomy

Everything ready for your upcoming Gemini Observatory proposal due in just one week? Need a hand with the technical side? Head over to our website to grab helpful links and slides designed to make the process easier for you! noirlab.edu/science/prog... #astronomy

From @noirlabastro.bsky.social: These images show disks of gas, dust, and other materials orbiting young stars. The disks may eventually coalesce into newborn planets. #astronomy @aura-astronomy.bsky.social

Missed the DRAGONS webinar on Gemini GMOS long-slit and imaging data reduction hosted by the US NGO last week? No worries! All the materials are now available. Visit our website and find the link to the webinar repository (slides, demos, Q&A). Check them out anytime! #astronomy

To see a meteor, you have to act fast. Sometimes they’re only visible for a few seconds! This meteor was captured above the Gemini South telescope, funded in part by the National Science Foundation and operated by NSF NOIRLab. #astronomy

Take a look at the new R400 grating available at Gemini North! It offers an improved throughput compared to the old R400 grating and it will be permanently installed on GMOS-N from August 1st, 2025 (HST). #astronomy

Grating B480 of GMOS-N is back in business! The grating has been secured in his holder position and is ready for science again at Gemini North. #astronomy

How busy are our Gemini telescopes every night? Due to its queue operations, we observe different programs, instruments, and weather conditions. Everything to maximize the resources we offer to our amazing community. Check all our time-lapse videos here: noirlab.edu/science/obse... #astronomy

From @noirlabastro.bsky.social: Remember that asteroid that’s been all over the news? Using Gemini South, astronomers constructed a 3D render of its hockey-puck shape 🥏 and determined it likely came from the main asteroid belt!🔗 noirlab.edu/public/news/...

The GMOS team at Gemini North has an update on the air bubbles found in the instrument's lens interfaces. More information and mitigation strategies are given here: www.gemini.edu/news/instrum... @noirlabastro.bsky.social #astronomy

Attention Gemini GHOST users: An issue was identified with the ThAr arc lamp in GCAL. The lamp was replaced, and PIs with data taken between 2025-02-14 UT and 2025-03-25 UT are advised to avoid calibration lamps for those dates. Details are given here: www.gemini.edu/news/instrum.... #astronomy

There is still time to get your 2025B Gemini proposal submitted. The deadline for the US is March 31st. Please reach out to us if you want to talk about your proposal or have instrument questions! More info here: gemini.edu/observing/ph... #astronomy

The US National Gemini Office is now on @bsky.app! We are part of NSF NOIRLab and support Gemini users in all the stages of the astronomical observing cycle, from proposal to data reduction. Our website is full of info and we will post content for the entire community! noirlab.edu/science/prog...

Did you know you can access reduced GHOST 👻 data directly from the Gemini Archive? Just search for observations made with GHOST. The reduced files will be highlighted in yellow for both the red and blue channels and have the suffix _dragons.fits or _calibrated.fits.

And thank you @emily.space for organizing and allowing the migration! 😉

Lol 🤣🤣🤣

Thank you @samdunham.bsky.social for donating an invitation so that I could join Bluesky!
